what happens if assad does go forth with the chemical warfare. senator mccain is discussing the role of the united states. >> i think we would be directly responsible. all of those who argued against intervention warned us that if we intervene these terrible things would happen. well, we did intervene and all of these terrible things, the consequences have been huge as we sat by and watched these 40,000 people massacred. it was very clear that there is more al qaeda and jihadists in syria. some of the arms because we didn't supply it supplied from saudi arabia and qutar gone to saudi rab gnaw and jihadist. because we didn't establish a safe zone for them to organize and basically have a benghazi they have been disjointed and unable to coordinate together. this is a serious crisis and we have to be prepared to put american troops, not to fight, not to be on the ground to fight but perhaps american troops to secure these weapon storage areas that we know where they are. no one wants american boots on the ground anywhere in the middle east any more.
